Hello World Tutorial

This guide takes a step-by-step approach to creating a new audio component and adding it to a simple audio pipeline.

At the end of this tutorial, a very simple audio signal amplifier will be running as a part of the playback pipeline implemented. You will be able to control the amplification strength from the command line.

The amplifier will log its basic activities to demonstrate use of the FW logging capabilities.

We will also inject a division by 0 instruction to the amplifier code to demonstrate how to collect and analyze the FW exception reports.

• Part II - Modifying the Topology & Driver
• Part III - Adding Run-time Parameter Control
• Part IV - Working with Exception Reports
